Nanocomposites
Nanotechnology or, for short, nanotech, refers to a field of applied science whose theme is the control of matter on an atomic or molecular scale.
Generally nanotechnology deals with structures 100 nanometers or smaller, and involves developing materials or devices within that size.
Nanocomposites are materials that are created by introducing nanoparticulates (often referred to as filler) into a macroscopic sample material (often referred to as the matrix).
After adding nanoparticulates to the matrix material, the resulting nanocomposite may exhibit drastically enhanced properties. For example, adding carbon nanotubes tends to drastically add to the electrical and thermal conductivity.
Other kinds of nanoparticulates may result in enhanced optical properties, dielectric or mechanical properties such as stiffness and strenght.
